Brandy reportedly played to a nearly empty arena in South Africa this week.

The Grammy Award-winning R&B star was a surprise guest at the Nelson Mandela Sports and Cultural Day concert in Soweto on Saturday, but nearly all of the event-goers were gone by the time she took the stage, according to the Guardian.

The 34-year-old "I Wanna Be Down" singer is said to have performed for about 40 audience members in FNB stadium, which has a 90,000-person capacity. Apparently there had been tens of thousands of people attending the earlier rugby and soccer matches, but most of them left while the musical segment — featuring four acts before Brandy — took place.

"Brandy [just] performed to an empty stadium. With the stadium lights on," tweeted Kabomo, a South African musician. "It was late. People didn't know there was a concert after the games. No one knew Brandy was around. Maybe a 40 people audience ... She sulked after two songs and walked off."

Brandy, full name Brandy Norwood, usually promotes her appearances on Twitter but didn't mention anything about her South Africa performance on social media either before or after the event. The newspaper site reported that the event's nationally televised broacast concluded just before Brandy's concert too.

On Aug. 20, her official website put up a post that seemed to intend to showcase a video of the performance. However, the actual post had no video and nothing beyond the show's basic details.

Perhaps because of the sparse turnout at the South Africa event, the singer has gone full force promoting her performances on both her Facebook and Twitter accounts. Neither she nor the concert promoters have made any statements about the event, according to reports.

In recent years — since a 2006 car accident that killed one woman and embroiled the singer in years of litigation — the "Brandy and Ray J" reality star has built up her acting career. The "Moesha" alum has had stints on "90210" and "The Game" and appeared in Tyler Perry's "Temptation: Confessions of a Marriage Counselor."

She will next be featured on embattled singer Chris Brown's upcoming album "X." Brown was featured on Brandy's track "Put It Down" from her sixth studio album "Two Eleven," which was released last year.
